Introduction: Anthropology is the science of body sizes evaluation in living people which is applied in both medical and non-medical professions. The main purpose of the study is the evaluation of foot growth from birth to the age of 10 in folk Fars girls of Birjand and to make an archive of the data and to study symmetry based on anthropometry and dermatoglyphy. Methods: In this study, t...

This study aims at determining the critical seismic intensity at which cracks are expected to develop in a concrete arch dam. This intensity is referred to as crack initiation intensity. The crack initiation intensity measure implies that earthquakes with the intensity measure higher than this value are expected to induce cracks in the arch dam. This quantity is an indicator for seismic evaluat...

An analysis was made of 78 pathologic specimens in which a right aortic arch was present. In four, the right arch was part of a double aortic arch. In 74 cases the right aortic arch was the only arch. The cases of right aortic arch could be subdivided into two groups as follows: (1) that with a retroesophageal aortic segment (three cases) and (2) that without a retroesophageal segment (71 cases...

Anterior and posterior crossbites are malocclusions in the sagittal transversal dimensions, respectively. As self-correction is rare these alterations, early interception recommended to allow normal occlusion facial development. This case report aimed discuss treatment of an eight-year-old boy with increased inferior third, who was submitted for rapid maxillary expansion a modified bonded appli...

This paper presents a stability investigation of a special-shape arch bridge with a span of 180 m. Its structure and mechanics are significantly different from normal arch bridges because of its single arch rib skewing across the girder, its hangers hanging unevenly along the arch rib with different aslant angle, and its arch rib being subjected to massive axial compression force, bending momen...

OBJECTIVES The purpose of this study was to determine the frequency of chromosome 22q11 deletions in patients with isolated anomalies of the aortic arch and its branches. BACKGROUND Chromosome 22q11 deletions are often present in patients with certain forms of congenital cardiovascular disease, including tetralogy of Fallot, truncus arteriosus and interruption of the aortic arch. Among patien...

OBJECTIVE To determine the most common maxillary and mandibular arch form and size in primary dentition stage. MATERIAL AND METHODS Four hundred thirty five preschool children were included in this study with an age range of 3.5-5.5 years old. Dental casts were digitized and landmarks for the measurements were identified and marked on each model. Ten points were determined on the dental arch....

Abstract We affirmatively solve the analogue of Lord Rayleigh’s conjecture on Riemannian manifolds with positive Ricci curvature for any clamped plates in 2 and 3 dimensions, sufficiently large dimensions beyond 3. These results complement those from flat (Ashbaugh Benguria Duke Math J 78(1):1–17, 1995; Nadirashvili Arch Ration Mech Anal 129(1):1–10, 1995) negatively curved (Kristály Adv 367:10...

Aim of this paper is to search and find ways and methods of constructivism teaching and learning ideas inteaching the architectural design studio. The objective is to extract all the positive things constructivism has to offer the architectural design studio for efficient teaching and effective learning. Although there are similarities in the curricula of training architects all over the world,...

Mandibular fractures are frequently encountered in oral and maxillofacial surgery. Open reduction and internal fixation (ORIF) is one of the treatments of choice (1-3). Maxillomandibular fixation (MMF) is usually performed during surgery (2-5). Recently, an arch bar was reconsidered as a means of providing additional stability to internal fixation in anterior mandibular fractures (1, 5). The ar...
